I’m new to this forum but here goes my problem. I purchased an STA2000B (Realistic) at an auction recently for the princely price of $5.00. I’ve set it up with some speakers and will use it while working in the garage. When I fire it up the speakers make a static sound then nothing. Meters show it is receiving signal and all lights work. BTW….this receiver is heavy…probably weighs 30 pounds.
